(volume 27 of Heidegger's Complete Works) presents Heidegger's lecture course delivered in the winter semester of 1928-1929 at the University of Freiburg, translated into English for the first time by William McNeil.

In this lecture series, Heidegger explores two major themes: the relation between philosophy and science and the relation between philosophy and Weltanschauung (worldview). Through extensive analyses of truth, unconcealment, and transcendence, he delves into topics that would expand into his later work.

From being-with and community to the phenomenon of world and the "play" of world, Heidegger covers a wide range of philosophical concepts with unprecedented clarity and profound insight. Introduction to Philosophy offer an encounter with a true master at work.
